IMPRVEMENT IN SPRING-BOLTS FOR WINDOWS.

Specification forming part of Letters Patent No. 104,465, dated June 2l,1870.

t Be it known that I, MonroN J UDD, of New Haven, in" the StateofConnecticut, have inp vented and made an Improvement in Spring`lVindowfBolts; and the following is declared to .be a correctdescription thereof.

Springfbolts have heretofore been inade for win dowsf The same aregenerally contained in a sheet-metal casel that is driven into a hole yi bored in the sash.` Bolts of this kind are not i durable, thesheet-metal case is liable to bend, the spring to bind por `becomedisplaced, and thebolt to break because of not being properly supportedat the outerfedge of the sash.

. My invention is made for obviating the fore-.

` going difficulties 'and othersthat will be here-` inafter named. i i iY In the drawings, Figure 1 is a section of part of a sash-frame andcasing, showing my spring window-bolt introduced therein, and Fig. 2 isan end View of the bolt and socket.

` The sash-mulliona and .casing b are prepared to receivethewindow-bolt, as hereinafter named. The bolticismade with a head, 2, acollar,'3, to prevent the bolt passing out of the socket d, a collar, 4,around which the end' of the spring e clasps, and collars 55l around theend of the shank portion 6 of said bolts. The socket d is madewith aflange, through which the screw f ispassed. The mullion a `is to bebored with a hole of a size and depth to receive thesocket d, the flangeof which is to be letin flush. rIhehole that isbored through the mulliona' is of a size to pass the collars 5 5.

If the collars 5 were of the same` diameteras Qtheshank 6, the carpenterin fitting the bolt in place, might bore a hole that would not besufficiently large to prevent the bolt being obstructed in itsv movementby the swelling of To guard against this j contingency, the collars 5are made of a larger diameter than the shank 6, so that when the holeis' bored of asize to allow these collars to the wood by moisture.

pass through, 'there will be ample room for the'free movement of the`shank 6. 4Ii'the spring e were not-attached by the collar 4to the boltc, it would be liable to be lost or might be improperly introduced. Byclaspingone l end around the bolt between the collar Land head 2, thespring is connected to said bolt;

but the bolt and spring are suficiently free to `assume their properpositions in the socket d,

and thefspring e, having a base of larger diamf eter than the end thatconnects with the bolt, is not liable to work into the hole throughwhich the bolt passes. The socket dfbecomes a rm support to the bolt end2, and sustains i head 2 of said bolt, sliding in the socket d, as`

projected by the spring e, as set forth. y
